2020 Buick Envision Complaints

I was driving and came to a stop at a light and all the sudden in my car just shut off. It took me a minute to try to turn it back on while cars behind me honking their horn. I’m assuming it has something to do with the electric due to the start stop button. I don’t have official incident report because I was able to get my car turned back on. I looked it up on the Internet and several people are having this issue.

We have two problems what we would call safety issues. First, all the sound in the vehicle was lost which included safety belt warning alarm, turn signal bells, door open alarms, etc. We were told by the dealership that it was a faulty amplifier. Secondly, the sunroof opened by itself, and is locked in the open position which makes the vehicle undrivable due to weather conditions and makes it an easy target for theft. The vehicle was locked and parked in our driveway when we noticed the sunroof was open. We know this occurred on it's own as we had just washed the vehicle and locked the doors. The next day we found the sunroof open and the doors still locked. This is a computer software issue within the vehicle as these issues occurred within a matter of days of each other. The sunroof opening on its own is a safety issue as a unsecure car is a problem, opening during traveling in a storm is a real threat to driving conditions.

The contact owns a 2020 Buick Envision. The contact stated that the front driver's side seat belt failed to extend and was inoperable. The vehicle was taken to the dealer, where it was diagnosed. The dealer informed the contact that the front driver's side seat belt ratchet was abnormally opened, causing the air bag module to fail. The dealer determined that the front driver's side seat belt assembly and the front driver's side air bag module needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 82,910. The VIN was not available.

Got in the vehicle to start the engine and the instrument cluster stop showing all readings of the gauges would not display the screen blacked out and none of the gauges were working. There were no warnings lamps or nothing out the ordinary the instrument cluster just went out. This is the first time it has ever done this.

The Air Bag, Parking Brake, Traction Control/StabiliTrak/Electonic Stability Control lights all came on while operating my vehicle. The lights did not go off, so I reported to the dealership. They determined it was an internal defect in the Inflatable Restraint Sensing and Diagnostic Module. This was not covered under warranty and appears to be a defect in the module. I believe this to be a serious safety concern and recommend a recall of this issue.
